Affleck has now spoken out to deny the Justice League rumours, telling 24 Hours Vancouver: "I'm not working on the Justice League [film]. One of the problems with entertainment web sites is that they need to fill pages, and that's how rumours get started…

"Justice League sounds really exciting, but it's not something I'm working on."

However, filmmaking duo Lana and Andy Wachowski are on Warner Bros's "wish-list" to helm the DC adaptation, reports Moviehole.

The studio is said to be "jazzed with Cloud Atlas", directed by the Wachowskis and Tom Twyker.

A Justice League movie could open to cinema in 2015 if Warner Bros begins production soon.
